The interaction of DNA repair factors ASCC2 and ASCC3 is affected by somatic cancer mutations
The DNA helicase ASCC3 is the largest subunit of the activating signal co-integrator complex (ASCC), and its DNA unwinding activity is required for the AlkBH3/ASCC-dependent DNA de-alkylation repair pathway. Here, the authors identify a minimal stable complex of the two ASCC subunits ASCC2 and ASCC3...

| Sumario: | The DNA helicase ASCC3 is the largest subunit of the activating signal co-integrator complex (ASCC), and its DNA unwinding activity is required for the AlkBH3/ASCC-dependent DNA de-alkylation repair pathway. Here, the authors identify a minimal stable complex of the two ASCC subunits ASCC2 and ASCC3, determine the complex crystal structure and further show that cancer-related mutations at the interface between both proteins reduce ASCC2–ASCC3 affinity. |
